Feeling of electric shock
I heard that the Science and Technology Museum of the Children's Palace in Furong District has many interesting things. The teachers of the Changsha Evening News Campus Journal Club led us to experience it.
The teacher led us into the Science and Technology Museum, and a glass ball called "Glowball" attracted us. As long as the glass ball is plugged in, there will be something like lightning inside. I touched the glow ball with my fingers, and my fingers seemed to have magic power, sucking a few "lightnings" near my fingers, like a magician. My fingers are moving on the glow ball, and "Lightning" moves with my fingers. The glow ball is very interesting and amazing, but why is this happening? The teacher unveiled the answer to us: In fact, those "lightning" are high-voltage electricity, because our human body is a conductor, so "lightning" will follow our fingers.
The device that most appeals to me is called "the feeling of electric shock." The device operates in such a way that one person shakes the generator rocker arm and the other person puts the palm of his hand on the hand-shaped metal plate that is attached to the generator. At this time, he feels the feeling of electric shock.
The teacher began to scare us and said: "The electric shock is so painful! Don't try if you are brave!" Some students listened and stepped back, but I was not afraid of it, but also volunteered to try. The teacher shakes the generator rocker arm and I slowly put my hand on the metal plate. When my hand touched the metal plate a little, I quickly shrank it back: "Ah! It’s so okay!" The teacher told us that this device is a feeling that we feel the electric shock, but the electric socket voltage in the home is very high, if the hand If you touch it, there is danger to your life.
Today's experience made me know the magic of the glow ball, and let me know the danger of electricity, let me understand that science has changed humanity.
